Hi Jim, When these flowers and if they turn out not mulberry, please post flowers photos. For me, plants that in different genera often have leaves with similar looking shapes. I find this so confusing at times. Good thing there are flowers & fruit to narrow down. Best wishes to you Jim! Laura

Laura: Good to have my submission confirmed as mulberry. Thank you for the Nabalus photos. I had no idea there was so much variation in rattlesnake root. In fact, I have (I believe) positively identified specimens of it that differ from any of these. Jim

Hi Jim, To my eyes these saplings in your own photos above look like a species mulberry (?) with serrated leaves. The ones in the previous ‘Understory plant’ post to my eyes, they appear to be of the Nabalus genus. Again until the flowers to confirm, my previous post with the suggesting Nabalus genus is still “Maybe”. And with only given photos to observe, I could be wrong. With plants, they fool me often. For now check out species Morus australis leaves specimens from the included link below. The second included link is for various species Nabalus genus. Thank you Jim for the follow up post! Best wishes! Laura https://www.marylandbiodiversity.com/viewSpecies.php?species=16640
